2017 Honda Ridgeline. The Honda Ridgeline is a unique pickup that employs car-like unibody construction in place of the rugged but unrefined body-on-frame setup that underpins its competitors. As a result, the Ridgeline provides a more comfortable ride and better handling than most pickups while still offering decent towing and hauling capabilities.
The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance Zone: Two Sets of Parallel Planes where the entire referenced surface must lie. Gauging / Measurement: Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel.
Roughness is measured in microns, Âµm or micro inches, Âµ. Ra measurement for a sample length âLâ is the mean height of the surface profile (peaks and inverted valleys). Ra is the arithmetic average value of the departure from profile from the center line.So, for four values: Ra / CLA / AA = W + X + Y + Z 4 Root Mean Square or RMS Roughness (Rq / RMS / Rs) , is another averaging measurement well known in statistics as the Root Mean Square value.a measurement for a sample length âLâ is the mean height of the surface profile (peaks and inverted valleys). Ra is the arithmetic average value of the departure from profile from the center line.
